Those would be igneous rocks. Extrusive igneous rocks.
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Rhyolititcen rocks.
Igneous rocks are formed by the solidification of molten materials.

The rock cycle.
Metamorphic rocks can form from both igneous and sedimentary rocks

Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
Sedimentary rocks make up about 75% of Earth's crust by volume, while igneous rocks make up about 15-20%. Sedimentary rocks form through processes like erosion, deposition, and cementation, while igneous rocks form from the cooling of molten magma.
